Abstract
Expression of concern for ‘Investigation of the biological activity, mechanical properties and wound healing application of a novel scaffold based on lignin–agarose hydrogel and silk fibroin embedded zinc chromite nanoparticles’ by Reza Eivazzadeh-Keihan et al., RSC Adv., 2021, 11, 17914–17923, https://doi.org/10.1039/D1RA01300A.
The Royal Society of Chemistry is publishing this expression of concern in order to alert readers that concerns have been raised regarding the reliability of the MTT plate image in Fig. 4B, the wound healing images in Fig 5B and the hemolysis plate image in Fig. 6B. An investigation is underway, and an expression of concern will continue to be associated with the article until a final outcome is reached.
